The Chastity Curve represents the lastest design in modern male chastity devices by the cutting edge company who developed the CB-2000 chastity devices this chastity device conforms with the natural flow of lines with the penis & body. The slim lines makes it easily worn under clothing. It is vented with curving lines & custom opening making it 100% hygienic. The material is that of the CB-2000 highly durable transparent polycarbonate, it is not only functional but extremely appealing as well! Some men find it possible to use the urinal while wearing "The Curve" while others find it more pratical to sit. Men who's job requires them to pass thru metal detectors will find this product a plus. It can be worn 24/7 and not interfere with their business routine. Just make sure you wear the plastic lock not a metal lock in order to be able to go through the metal screening. Because of the design there are no uncomforatble belts, straps or chains needed with "The Curve". The curve consisits of two main parts, the cage portion and cuff ring. They easily slide together by way of two guided pins and a locking pin. The guide pins extend from the cage portion. Once you find the right amount of spacing, simply use a pair of side cutters pliers to snip the ends of the guide pins & then smooth the edges with an emery board. The locking pin is slightly recessed into the body cuff. There are various sizes spacers that can be used for an individual custom fit. Also, for additional comfort, we suggest using baby oil after showering, apply to the penis with a cotten swab.
